In my classes, at any level, and when we talk about values, I always bring examples such as those of Martin Luther King, Jr, Mandela or Gandhi, among others, who dedicated their lives to the cause of peace and to improve the lives of others. One of the problems I see in the USA, specially in its educative system, is the tendency to take militaries and policemen as examples of heroes and values. I do not like to take those who use violence to solve problems as a model to follow.
